IMPROVEMENT IN HARVESTERS.

To all whom it may concern Be it known that I, G. W. RIoHARDsoN, of Grayville, in the county of White and State of Illinois, have invented a new and useful Improvement in Grain and Grass Harvesters; and I do hereby declare that the following is a full, clear, and exact description thereof,which will enable those skilled in the art to make and use the saine, reference being had to the accompanying drawings, forming part 0f this specification, in which- Figure 1 is a side View ot' a harvester with my improvement applied to it; Fig. 2, a rear view ofthe same; Fig. 3, a plan or top view of the same.

Similar letters of reference indicate corresponding parts.

This invention relates to a new and useful improvement in connecting the linger-bar to the main frame of the machine, u hereby the points ot' the fingers or guards, and consequently the points ofthe cutters ofthe sickle, may be elevated in a greater or less degree, as circumstaines may require, and firmly retained in the position in which they may be set or adjusted.

A replesents the main frame ot'aharvester, and B B the wheels on which it is mounted. These parts may be constructed in the usual manner, and therefore donot requirea minute description.

O represents the finger-bar, which may also be constructed in the usual way, and is provided with the ordinary fingers. 'lhe inner end of the 1inger-bar hasashort bar, D, tirmly attached to it at right angles, and the front end of bar D is connected by ajoiut, a., with a bar, E. The bar E is parallel, or nearly so, with the sidel of the main frame A, and the front end of the bar E is provided with an eye, b, in which an eyebolt, F, is fitted, forming a universal joint. The eyebolt F is provided with a screw-shank, c, which passes through the front cross-bar, d, of the mainframe A, and has two j ain-nuts, e e, upon it, one at the front, and the other at the rear, side of the bar d,

(see Figs. l and 3.) On the rear part of the bar D there is an upright lip, c', iu which the rear end of a rod, E", is ttedby being bent inhookformorotherwise. Thefrontendofthis rod passes through a lip, f, on the bar D, and has jam-nutsg upon it, oneiu front of, and the other at the rear ot', the lip.

G represents a bar, one end of which is connected by a pivot, 7L, to a plate, t', at the center of the rear of the main frame A, and the opposite end is fitted loosely on the rear part ofthe rod EX. By this means the linger-barv isattached to the main frameA,and the -inner end ofsaid bar isallowed to rise and fallequally as well as the outer end, and it is allowed to conform perfectly to the inequalities ot' surface over which it may pass. This mode ofconnection, however, is not new, and it may be seen in various harvesters in use, such as the Buckeye, for instance.

The novel feature consists in the rod EX and the joint c, which connects the lmrD with the bar E. lt will be seen by referring lo Fig. 1 that by screwing up the jam -nuts g g, and thereby depressing the frontend ofthe bar I), that the front edge ofthe finger-bar, and consequently the front ends ofthe lingers which are attached lo said linger-bar, will be depressed, and by unscrewing the nuts g g the front ends ot' the fingers will be elevated. Thus, by this simple means, the sickle may be made to cut more or less close to the ground, as the nature of the latter will admit, and the adjustment may be made with the greatest facility.

I claim as new- The rod E", in combination with the bars D E, connected by a joint, a, when arranged in connection with the finger-bar O and bar Gr, and all applied to the main frame A, substantially as and tor the purpose set forth.
